Development of the Systems provides reception of the multitude of information and improvement of theiranalysis for diagnostics of aviation techniques. However theoretical bases deficiently are motivated forstructure and analysis of information. On modern stage of evolution of the artificial intelligence the trend istracked the outrun of technological (practical) of the facilities of the development of the intellectual systemscomparatively their theoretical developments. In this connection in article the idea is emphasized thatclassical approaches to the analytical bases of the cybernetics have grown old. Accordingly by the base forensuring of functioning of the automatic diagnostics systems requisite to consider the ways (the strategies) ofdecompositions and creature structure of the knowledge base in relation to of the concrete aviation object.However use of the syntheses of the deductive and of inductive strategy shaping the structure of theknowledge’s can be insufficient in some cases of making of the diagnostics system of the complex object ofthe aviation techniques with depth diagnosis at the constructive node. For this case on each of levels ofstructurization of the knowledge base, authors offer to apply also strategy of parallel (horizontal)decomposition of object of diagnosing concerning its behaviour at transition from one stationary operationalregimen on another. As a base paradigm of methodology of the structural analysis and formation of a field ofknowledge by authors are proffered to use generalised objective - the structural approach, which developedto technological and program realisation.

The results of simulation of resulting acoustic emission signals at friction surfaces of the composite material were shown. It was shown that at increase of contact interaction area of the friction unit is increase of the average amplitude of the acoustic emission, their standard deviation and variance. The approximation expressions for the regularities of changes of the amplitude parameters of acoustic emission signals which are generated by the increase of the contact interaction area of the friction unit were defined. The comparison of experimental results with theoretical research was conducted. It was shown that the most sensitive parameter to change the contact interaction area of the friction unit is the variance of the average amplitude of the formed resultant acoustic emission signal

uk_UA
A static analysis techniques were combined with model-based deductive verification using solvers of the static model theory (SMT) to create a framework that, given an aspect of analysis of the source code, automatically generated with an analyzer outputting a conclusion information about this aspect. The analyzer is generated by translating of a program collecting semantic to outlined formula in first order over a few multiple submitted theories. The underscore can be looked as some set of holes or contexts corresponding to the uninterpreted APIs invoked in the program. As the program makes an import of the packages and uses classes’ methods of these packages, it is importing the semantics of API invocations in first order assertion. The analyzer is using these assertions as models and their first logic order formula incorporates the specification behavior (its negation) of the described programs. A solver of SMTLIB formula is treated as the combined formula for “constrain” and “solve” it. The “solved” form can be used forlogic errors (security) identification Android-based Java-programs. The properties of Android security are represented as constraint and analysis aims to show the respecting for these constraints.

Computer clouds are using in health science for its data collections, manipulations and providing security needs in communications to exchange. The clouds distribution data character is using in science applications created to evaluate the data of the health-care. The science programs like medical visualization, genetic and protein conclusions, map-drag therapy and clinical decisions systems of support (CDSS) require high performance messaging libraries with minimum computer and communication spends and the effective utilization of the resources. The highperformance Java sockets (HPJS) encapsulate the needs of message high communications between cloud platforms science applications. HPJS effectively uses the Java socket realization for high-performance inner-process communications. With single-copy protocol, re-usability of the thread and communication overhead reduction, HPJS can use the message exchange in two times quickly to conventional buffered communication libraries.

The article examines methods of images analysis based on computer vision. We made a comparison between the detectors of feature points determined by Harris and Kanade–Lucas–Tomasi (KLT) methods. Found points are represented by Speed-Up Robust Feature (SURF) descriptor and then used to determine homography matrix. Analyses of accuracy of visual navigation is done by estimation of a camera rotation angle via factorization of homography matrix obtained from two detector methods. Errors of visual navigation follow the normal distribution for the given sample.

The influence of a shape of initial turbulence power spectrum on a velocity spectrum of moving particles caused by the turbulence in clouds and precipitation is analyzed in this paper. The particles contemplated are scatterers of electromagnetic field. The probable deviations of turbulence spectrum from Kolmogorov-Obukhov model are considered. Scatterers' velocity spectrum is a basis of Doppler spectrum by weather radar. That is why the results obtained must be taken into account both for construction of models of signals reflected from turbulized weather objects and for interpretation of remote sensing measurements in clouds and precipitation by Doppler radars

Purpose: One of the most actual trends in program code protection is code marking. The problem consists in creation of some digital “watermarks” which allow distinguishing different copies of the same program codes. Such marks could be useful for authority protection, for code copies numbering, for program propagation monitoring, for information security proposes in client-server communication processes. Methods: We used the methods of digital steganography adopted for program codes as text objects. The same-shape symbols method was transformed to same-semantic element method due to codes features which makes them different from ordinary texts. We use dynamic principle of marks forming making codes similar to be polymorphic. Results: We examined the combinatorial capacity of permutations possible in program codes. As a result it was shown that the set of 5-7 polymorphic variables is suitable for the most modern network applications. Marks creation and restoration algorithms where proposed and discussed. The main algorithm is based on full and partial permutations in variables names and its declaration order. Algorithm for partial permutation enumeration was optimized for calculation complexity. PHP code fragments which realize the algorithms were listed. Discussion: Methodic proposed in the work allows distinguishing of each client-server connection. In a case if a clone of some network resource was found the methodic could give information about included marks and thereby data on IP, date and time, authentication information of client copied the resource. Usage of polymorphic stego-watermarks should improve information security indexes in network communications.

The article researches the echo-signals of weather radars. The mathematical models of echo- signals and Doppler spectra, which are taking into account a microstructure and dynamics of the scattering volume of a weather formation, parameters of a sounding signal, and conditions of probing are developed. The problem of imperfect particle response on the turbulence contribution to Doppler spectrum is solved. The concept of radar signal computer simulation is substantiated and implemented. This concept does not require the preliminary suppositions about models of the statistical characteristics of a reflected signal. The models and parameters of weather formation (in particular, the parameter of a turbulence intensity in the radar volume) are being used as input data Figs
